Hi,
I'll be taking Quantum Mechanics A, Electromagnetic Theory I and PDE next semester. However, in the course description, PDE is a corequisite for QM and Electromagnetic. I wanted to know what PDE topic should I read up on during the holiday that i might encounter in QM or EM before the...
The classes are quite big actually.
for this year.
statistical physics - roughly 48 students enrolled of a total of 60 spots
computational physics - 30 out of 40 spots.
the conflict was created during my second year and there is nothing i can do to fix this even before scheduling for my...
Computational physics II
both are required for my program.
Just say i informed them but they can't/won't do anything about, then what other options do i have?
Hi,
I just discovered that next year, i will have two courses in the same time slot. I supposed to take one of them (statistical physics) this year (third year) but due missing prerequesite which I'm taking now, I'm unable to. These courses are offered only once a year. i can't graduate next...
Hi,
I'm a third year computational physics student at UofA.
I started looking into grad school for physics but I'm not so sure if i can make it into any good grad school with my not so good gpa (around 3.4 ish).
I have no research experience, however I'm planning on being an assistant for...
& is the bitwise and operator, x &= x-1; is the same as x = x & (x-1);
if an unsigned int x = 5; then
5 = 101 in binary and (x-1) = 4 = 100
so after evaluating, x = 100 in binary or x = 4 in decimal.
Hi,
After hrs of googling still couldn't find the answer to my question. I'm hoping i get better luck positng it here. Any C/C++ out there please help!
1)
a) Given an unsigned int x, what does x &= x-1; do and why does it work?
I know what x &= x-1 does but to explain why does it work...
Hi,
i'm stuck on this question for my hw, please do give any advice/suggestions .. thanks!
For Berthelot equation of state P = RT/(v-b) - a/(Tv^2)
where T is the thermodynamic temp, a and b are constants, R is the Universal gas constant.
a) Show that Lim_(T->infinity) v/T = R/P...
Hi,
It was a big mistake leaving my assignment till the last minutes. Now I'm stuck on a few questions and got no where to turn to except the net.
Please do give any hints you may have..
Thank You!
1. Let A subset {1,2,3,...,25} where |A| = 9. For any subset B of A let SB denote the sum of...
Hi,
This is one of the question from my hw, i don't even understand what it's asking? Please shed some light on it.. thx
what is the smallest value of k such that any integer postage greater than k cents can be formed by using only 4-cent and 9-cent stamps? Show that k cents in postage...
hi,
From what i understand is that photons lose engery after being reflected off some material due to conservation of momentum (hitting electrons...). If they loses energy then their frequency is smaller, but how come when u look at a mirror you don't see a change in color the image in the...
hi,
i have this problem for my discreet math class, after an hr and still didn't figure it out so the next best thing is to post it here to get some advices that might jumpstart my brian.
anyway here it is (a bit long).
John and his wife, Mary, went to a dinner party with four other...
hey
here is the question,
suppose an explorer set out on a ship traveling to some stars at a constant velocity of 0.9c. every week mission controller and explorer each transmit status report to each other and acknowledge receipt by transmitting a confirmation signal back
when does...
In my opinion, i would say aerospace engineering is the best. You get to design and play with all the nice toys (airplane, rockets...).
ME is ok..
but stay away from EE. not fun from what i heard..
hey,
I'm on my second year in college and i recently transferred my program to honor computational physics (almost done the first year for it). Anyway i was wondering what kind of job would i be doing if i only have a bachlor degree in it (average salary too would be nice if you have info on...
hi
i got this question for homework and after a few hours of head scratching, i still haven't figure it out...
the question is, prove that the set of all 2x2 matrices with determinant zero, is not a subspace of M2x2 (<-- M2x2 means just a notation for 2x2 matrices).
someone please give...
ahh my teacher throw another similar question... exact wording as the above, but this time is light instead of sound wave. doppler effect behave similarly in all waves right? so the answer would be the same as the sound example.?
thx
but the observer still see the speed of the laser to be c.?
so the speed the stay the same, only the wavelength change according to the observer perspective??
i'm jux wondering would a laser mounted on a spaceship traveling at half the speed of light... wouldn't this make the speed of the laser on the ship change to 1.5c??
thx
i'm reposting this here because for some reason my post moved to grade k-12 forum... btw this is a first year University physics question...
this is from my physics assignment... after pulling half of my hair, i still couldn't figure it out...
my answer for part a) is greater and lower...

not sure tho...
thx

Just to add, if it's not a trick question, the answer is "never". The same side of the faces the Earth all the time, so there would be no tide.
that's what i thought too, since the high tides remain in the same place, the period wouldn't exist...
btw this question is from first level...
Hi
There is a question in my physics book that kept me thinking but still can't find a solution...
here is the question: The Moon is observed to keep the same side facing the Earth at all times. If the Moon had oceans, how much time would elapse between it's high tides?
since we know...
